This invention relates' to a 'mixin'g chamber attachment, preferably adaptedfor connection in an overhead shower line. w

The primary object of this invention is to provide a mixing device for bath salts, water softeners, soap,pperfume or thelike, to be introduced into a shower in selected quantity, which device can be quickly manipulated to change the shower from pure water to any gradual or complete solution, and whichcan be easily installed into the overhead conduit of a shower outside of the wall, and can'be quicklyrefi'lled.

We are aware that-some--changes may be made in the generalarrangements;andflcombinations of the several devices and parts, a s well as in'the details of the construction thereof withoutdeparting from the scope of the present invention asset forth in thefollowiii pecificationl," and Otto and Edward-H..Warne,

' water for the. shower;

tachably secured intorsaid huh I' I; g chambercontains the substance to be dissolved in the A chamber outlet I4 extends from the: chamber hub- II into the long as defined in the -followifig claims; hence we do not limit our invention to the exact arrangements and combinations of the said device and parts as described in the said specification nor do we confine ourselves to the exact details of I the construction of the said parts as illustrated in the accompanying drawings.

With the foregoing and other objects in view, which will be made manifest in the following detailed description, reference is had to the accompanying drawings for the illustrative embodiment of the invention, wherein:

Fig. 1 is a side view of our device installed on a shower line.

Fig. 2 is a sectional view of our device.

Fig. 3 is a side view of our device, and

Fig. 4 is a bottom plan detail view of the section and the chamber of our device.

In carrying out our invention we make use of a straight conduit section I, the intake end 2 and outlet end 3 of which are threaded for connection to the ends of overhead pipes 4 of a shower. These pipes 4-protrude from the wall 6 so that it is not necessary to disturb the concealed portion of the piping and the wall.

This conduit section I has a pair of passages. A passage I extends through from about the intake end 2 to the outlet end 3 of the conduit section I. Another passage 8 extends from about the intake end 2 to a side port 9 substantially intermediate between the ends of the conduit section I. The side port 9 extends to one side of the conduit section I into about the middle of a cylindrical chamber hub II on said side of the conduit section I.

A mixing chamber I2, preferably made of a transparent material, has an open mouth I3 threaded on its outer periphery so as to be depassage. I; This-chamberloutlet I4: is offset both transversely and longitudinallyrof' the section with respect-to the. intake so aSfllQfillDW simultaneous and. proportionate, control of, water passage through ,thegconduitiseetionLand the chamber I2.

This. simultaneous; and; proportionate" control accomplished: by a cock; valve; I fi which, turns in a generally cylindrical SVEIIVGi'SQCkBtf II;.which extends transversely rof theconduitxs'ection I, across-both passages, l andafir'. :This: valve It has a pair of spaced. valvelportszorholes I8 and I9 across it alignedrespectively' withthe passagesl and 8. -"I heseport holes I'Band Iaare oppositely inclined an'd angularly. 'ofiset so'that as one hole is aligned with its passage, the other hole completely blocks the other passage. The valve It extends to the outside; it is suitably packed and has a handle 2I on its outside end to facilitate manipulation.

The chamber intake 9 is threaded and has detachably secured in it a conduit 22, which extends to the vicinity of the bottom of the chamber I2. The chamber outlet I4 hasa screen bowl 23 thereon to preventthe passing of solids out of the chamber. The chamber I2 has a collar 26 on its outer periphery which presses a packing gasket 24 against the lower face of the hub II, to seal the chamber.

The unit is easily installed, by first removing the shower head joint, and interconnecting the conduit section I. Then the mixing chamber 2 is suitably filled with the substance to be mixed in the shower and it is then screwed in place.

"Thereafter the person taking a shower turns the handle 2I to select the kind of mixture wanted. For instance the valve may be turned to fully open passage I9 to the chamber intake 9 and close the other passage I completely, thus forcing all the water through the chamber I2, which results in a dense solution. Th handle 2| can be turned partly, so as to direct some water through the chamber I2, and some water directly through the passage I, in inverse proportion. Namely the closing of the passage and opening of the other passage are always simultaneous and proportionate. When the sid conduit 8 is shut ofi completely, the rinsing water passage Iis fully opened, conducting pure water to the shower.

The installation and operation of this device requires no special skill or fine adjustment, it can be readily accomplished by the average user.

We claim:

1. A mixer attachment for a bath conduit comprising a conduit section, means on each end of said conduit section to interconnect said conduit section in line continuously in said bath conduit, an attachment flange formed on one side of said section conduit between said ends thereof, a hollow vessel adapted to contain asoluble cleaning compound having an open end thereof detachably secured to said flange, a valve seat across said conduit, a singlepassage leading from an end of the conduit into said valve seat, said valve seat having a pair of outlet ports generally axial to said conduit, a passage leading from one of said outlet ports to the other end of said conduit, a bypass passage leading from the other out; let port to and through the side of said conduit on which said flange is located and being directed into said vessel, and an outlet passage leading through said side of said conduit from'saidopen endof said conduitinto said-first passage between said first'mentioned outlet and the other end of the conduit, and a valve adjustable in said valve seat having a pair of valve'passages therethrough angularly offset relatively to one another for selectively and proportionately communicating' said single passage with the respective outlet ports. i

2. A mixer attachment for a bath conduit comprising a conduit section, means on each end of said conduit section to interconnectsaid conduit section in line continuously insaidbath conduit, an attachment flange formed on one side of said section' conduit betweenzsaid ends thereof, a hollow vessel adapted "to contain a soluble cleaning compound having .an' open end thereof detachably securedto'said flange, a valve seat 4 across said conduit, a single passage leading from an end of the conduit into said valve seat, said valve seat having a pair oi. outlet ports generally axial to said conduit, a passage leading from one of said outlet ports to the other end of said conduit, a bypass passage leading from the other outlet port to and through the side of said conduit on which said flange is located and being directed, into said vessel, 5 and an outlet. passage leading through said side of said conduit from said open end of said conduit into said first passage between said flrst mentioned outlet and the other end of the conduit, an extension conduit extended from said bypass passage inwardly of said vessel and terminating near the closed end of said vessel, and a rotatable valve in said valve seat having valve passages therethrough for con- 'necting said first passage with the respective valve outlets at will, said valve passages being ofiset angularly with respect to one another for selective and proportionate communication between said first passage and therespective valve outlets.
